Abstract
It has been shown that addition of fennel in the diets of domestic animals has positive and beneficial effects on growth and meat production traits. Thus, the purpose of current study was to investigate the effect of adding fennel in the ration on growth characteristics and on insulin-like growth factor 1 (IGF1) gene expression in muscle tissue of Kermani lamb. Feeding of animals were performed with three levels of fennel including zero, 10 and 20 g/kg dry matter (DM) for 90 days. After slaughter, small pieces of tissues were removed and rapidly transferred to a nitrogen tank. Then, total RNA extracting and the Real-Time PCR reaction was performed. Results showed that as the level of fennel in the diet increases the amount of IGF1 gene expression also increases significantly in humeral muscle and femur (leg) muscle tissues (p < 0.05). In animals fed with fennel, femur muscle weight, back muscle weight, lean meat weight, final weight, warm carcass weight and live daily gain were greater than in animals fed with diet without fennel (p < 0.05). According to the findings of this investigation, it can be concluded that fennel, by creating positive effects on IGF1 gene expression can be used to improve muscle structure.

Abstract
Undernutrition suppresses the growth of skeletal muscles and alters the expression of insulin-like growth factor 1 (IGF1), a key mitogen, and myostatin, a potent inhibitor of myogenesis. These changes can explain, at least in part, the reduced growth of skeletal muscles in underfed lambs. We have recently identified a myostatin splice variant (MSV) that binds to and antagonizes the canonical signaling of myostatin. In the present study, we hypothesized that the expression of MSV would be reduced in conjunction with myostatin and IGF1 in response to underfeeding in skeletal muscles of sheep. Young growing ewes were fed either ad libitum or an energy-restricted diet (30% of maintenance requirements) for 28 d. This regime of underfeeding resulted in a 24% reduction in body mass (P < 0.001) and a 36% reduction in the mass of the semitendinosus muscles relative to controls (P < 0.001) by day 28. The concentrations of MSV and IGF1 messenger RNA (mRNA) were reduced (both P < 0.001), but myostatin mRNA was not altered in semitendinosus muscles. Unlike the reduced expression of mRNA, the abundance of MSV protein was increased (P < 0.05) and there was no change in the abundance of myostatin protein. Our results suggest that undernutrition for 28 d decreases the signaling of myostatin by increasing the abundance of MSV protein. Although this action may reduce the growth inhibitory activity of myostatin, it cannot prevent the loss of growth of skeletal muscles during undernutrition.

Abstract
We tested the hypothesis that the dietary energy-dependent alterations of the rumen papillae size are accompanied by corresponding changes in systemic insulin-like growth factor (IGF)-1 concentration and in rumen papillary IGF type 1 receptors (IGF-1R). Young male goats (n=24) were randomly allocated to two groups (n=12) and fed a high level (HL) metabolizable energy [1200 kJ/(kg(0.75).d)] or a low level (LL) [500 kJ/(kg(0.75).d)] diet for 42 d. The concentration of ruminal total SCFA did not differ between the groups, but the molar proportion of butyric acid was enhanced by 70% in the HL group (P<0.05). Both the length and width of the papillae were greater (P<0.05) in the HL group, and the surface was 50-100% larger (P<0.05) in the tissue sampled from the artrium ruminis, the ventral ruminal sac and the ventral blind sac. Transport of Na+ across the rumen epithelium, which is amiloride sensitive, was higher (P<0.05) in the HL than in the LL group. Furthermore, the plasma IGF-1 concentration was about twofold higher in the HL group (P<0.05), and the maximal rumen epithelial IGF-1R binding was also higher in the HL (P<0.05) than in the LL group. IGF-1R mRNA and IGF-1 mRNA were detected in rumen papillae; however, they were unaffected by dietary treatments. DNA synthesis and cell proliferation of cultured rumen epithelial cells were higher (P<0.05) after IGF-1 treatment (25 or 50 microg/L) compared with those in the medium without IGF-1. Thus dietary energy-dependent alterations of rumen morphology and function are accompanied by corresponding changes in systemic IGF-1 and ruminal IGF-1R.

Abstract
The objectives of this study were to investigate if insulin receptors (IR) and insulin-like growth factor-1 receptors (IGF-1R) could be detected on bovine leukocytes using fluorescence antibodies and flowcytometry, and use this method to investigate whether the amount of receptors differed among heifers at different ages. Twenty Danish Holstein heifers in the following three age groups were included in the investigation: (1) heifers aged 25-45 days (n = 8), (2) heifers aged 185-205 days (n = 7), and (3) heifers aged 780-900 days (approximately one month prepartum; n = 5). Antibodies against human IR and IGF-1R were used for indirect immunofluorescence staining of cells, and were found to cross-react with the bovine receptors. IR were found on lymphocytes, monocytes, and neutrophils in all animals, while IGF-1R were found only on monocytes and neutrophils. The percentage of IR+ lymphocytes was almost doubled from stage 1 to 3 (34% versus 57%) and IR expression on lymphocytes and monocytes increased significantly (P<0.01) from 6.80 and 13.60 to 8.24 and 17.50 in heifers aged 185-205 days and heifers aged 780-900 days, respectively. No differences were observed for neutrophil IR or IGF-1R expression. In conclusion, surface IR and IGF-1R can be detected on bovine leukocytes by flowcytometry. Interestingly, the highest numbers of IR were found in heifers one month prepartum. The regulation of IR and IGF-1R expression on bovine leukocytes, and their role in host immunity, needs further investigation.

Abstract
Physiological adaptations induced by dietary restriction might include the modulation of the insulin-like growth factor 1 (IGF-1) axis. We investigated the effects of dietary restriction on aging-dependent changes in plasma level of IGF-1 and gene expression levels of type-1 IGF receptor (IGFR), insulin receptor substrate-1 (IRS-1), and IGF-1 in the diaphragm and quadriceps femoris muscle (QFM) of male F344 rats. The animals were fed ad libitum throughout life (AL), or provided with 70% of diet of AL rats from 6 weeks of age (DR). The plasma IGF-1 and steady-state levels of the genes were quantified by radioimmunoassay and the reverse transcription-polymerase chain reaction method, respectively. Immunohistochemical analysis in tissue sections was also performed for IGFR. Our results showed that dietary restriction: 1) decreased the plasma level of IGF-1; 2) increased the steady-state level of IGFR-mRNA at 6 and 16 months of age. and the peptide level at 6 months; 3) maintained IGF-1- and IRS-1-mRNA at a level similar to that in AL rats; and 4) delayed or inhibited an aging-dependent increase in IGFR-mRNA in the muscles. The present results suggest that dietary restriction could modulate IGF-1 signaling by augmenting local tissue response to IGF-1 and by maintaining the local production of the peptide, even though plasma IGF-1 is reduced.

Abstract
Insulin and IGF-I binding has been studied in brown trout (Salmo trutta) wheat germ agglutinin semipurified receptors from embryos (organogenesis), larvae (yolk sac), juveniles (2.98 +/- 0.21 g bw) and adults (111.6 +/- 6.92 and 522 +/- 53 g bw). Embryos and larvae were sampled at 5 and 12 weeks after fertilization (December 1999 and February 2000) and juvenile and adults were taken simultaneously (July 1999) and under the same feeding conditions to minimize potential nutritional and seasonal effects. Insulin receptor number was maximal at 12 weeks (144 fmol/mg glycoprotein) and progressively decreased in subsequent samplings. No alterations in affinity were detected (K(d) range, 0.21-0.32 nM) and changes in number of receptor paralleled changes in total specific binding. IGF-I receptor number was highest at 5 weeks (1044 fmol/mg) and was significantly higher than values for insulin in all samplings. The affinity of IGF-I receptor did not change (K(d) range, 0.11-0.18 nM) but was consistently higher than that for the insulin receptor. A more rapid decrease of IGF-I binding and receptor number was found with age. However, the ratio of insulin/IGF-I binding established in 12-week-old larvae (0.18 +/- 0.01) was thereafter maintained at very similar values in juveniles and adults (0.15-0.17). Tyrosine kinase activity (TKA) for insulin receptors ranged between 136 and 183% and there were no significant changes with age. For the IGF-I receptor, TKA ranged from 174 to 281% and was significantly higher in 5-week-old larvae coincident with the highest levels of receptor number and declined gradually in parallel with binding levels. In conclusion, the greater abundance of IGF-I receptors during embryonic and larval development is maintained throughout juvenile and adult stages. This would suggest a key role for IGF-I in the growth and metabolism of trout muscle.

Abstract
IGF-I receptors were characterized in leg and breast muscles from 1- and 7-week-old chickens selected for high (HG) or low (LG) growth rate. Following whole muscle solubilization, receptors were partially purified by wheat germ agglutinin (WGA) chromatography. IGF-I and insulin binding did not differ between genotypes, but significantly decreased with age, without any change in receptor affinity. In the older birds, insulin binding was lower in breast than in leg muscle, whereas IGF-I binding was similar. Using the artificial substrate poly(Glu-Tyr) 4:1, the IGF-I-stimulated tyrosine kinase activity of the receptors was measured and compared between genotypes (at 1 week), and in HG chickens between muscle types (1 and 7 weeks) and ages (in leg muscle). It was not modified by any of these factors. We conclude that: (1) IGF-I and insulin receptor number do not differ between genotypes, (2) the number of both receptors decreases with age, and (3) in 7-week-old birds, breast muscle could become less responsive to insulin than leg muscles, following a decrease in receptor number.

Abstract
The insulin-like growth factors (IGFs) are considered to have a role in the regulation of renal growth and development. The purpose of the present study was to evaluate the effect of nutritional stress on IGF binding in ovine kidney at different postnatal ages. Binding of IGF-I and IGF-II to kidneys of fed and fasted sheep was characterised using histological autoradiography, competitive binding assays, and SDS-PAGE. Nutritional regulation of IGF-I binding was restricted to cells of the proximal tubules of two and 14-day-old lambs where we identified an IGF binding protein which was upregulated in response to fasting and where IGF-II binding was also slightly enhanced. Ontogenetic changes occurred in the glomeruli where IGF-I binding peaked at 6 months (P < or = 0.001), and IGF-II binding increased to 4 months and then plateaued (P < or = 0.01). In the medulla, IGF-II binding was highest at 4 and 6 months (P < or = 0.05). From these studies, we conclude that the IGF axis may play a role in the regulation of the metabolic response to fasting in the kidney of young lambs. Furthermore, the changes with age which are described may reflect a transition period at 4-6 months, from an initial promotion of kidney growth and development in young lambs to establishment of the metabolic and clearance functions in the adult animal.
